Describe the dream Cosimo had in chapter twenty-nine.

In chapter twenty-nine, Cosimo daydreams that a wilted and disillusioned Napoleon comes riding back to his tree, and having realized the error of his ways, asks Cosimo for the Constitution he wrote, and that everything starts again from the beginning, so that the ideals that bring about a better society can be the motivation and fruit of whatever struggle men give their lives for.
